In reply to benoist:
I would not recommend wild camping around the cuttings, unless the locals have changed their habits in the last few years... and don't camp under a cliff whose top can be accessed by said locals as they'll chuck things off.
I used to wild camp done there until returning to our normal spot to find a car had been pushed off the cliff above and was now embedded where my tent would normally be.
The lower boulder field below the cuttings has some good spots, and we've even had 4 tents up (put up after dark) on the grass ledges to the left as you look out from the Cove House Inn with no one bothering us, but then we are quiet, and leave no trace (there was even a portaloo unit for washing in!)
